"OpenSolaris has launched a new project, Flexible Mandatory Access Control, to integrate the Flask/TE security scheme into their OS. This is the same underlying model implemented by SELinux, and follows other cross-platform Flask/TE integration projects such as SEDarwin and SEBSD. This is very exciting in terms of establishing compatible security across operating systems, particularly for Mandatory Access Control, which has traditionally been narrowly focused and generally incompatible. With FMAC, we're closer to seeing truly ubiquitous, cross-platform MAC security."

Contrary to your assertion that Trusted Solaris was abandoned, all of its technology has instead been integrated into the main release. In addition, if you actually take the time to read many discussions on opensolaris.org about the Trusted Extensions it brought, you would see that government customers especially liked them.

So, I assert that your source of information needs review.

Right, So Trusted Solaris technology hasn't been integrated into the main release. "

No, technology from Trusted Solaris has been integrated into the main release. Maybe not the GA release yet (though I thought it was) though.

One of the main things that was dropped from Trusted Solaris is fine grained labeling (which some Sun people claim is unnecessary). Trusted Extensions simply does not do the same thing that Trusted Solaris did. I have personal knowledge of ex-Sun customers that found Trusted Extensions inadequate for their uses.

Regardless of personal knowledge of such things, it's hardly news that some folks find certain technology inadequate for their uses. Some people like things, some don't. Some people have their needs met, some don't.

Just as many people find SELinux inadequate for their needs. I certainly do. I absolutely despise SELinux and believe it to be the worst thing ever. Maybe the concept is great, but the implementation in most GNU/Linux distributions is horrid and unusable.

Granted many components of Trusted Solaris has been brought into Trusted Extensions (e.g., trusted X, labeled networking, etc). I may have been a little harsh by saying 'abandoned' and for that I apologize.

That was my main point. Sun engineers took the "best of breed" technology from Trusted Solaris and integrated it. Trusted Solaris, to the engineers, was really just Solaris + Trusted Extensions from what I've been told.
